The Ocarina of Time Switch 2 remake ROM has reportedly been extracted and is circulating outside Nintendo’s official channels on the game’s launch day, according to a jailbreak group known as ONE. The group says both the original 1.0.0 release and a 1.1.1 update have been dumped, with the update alone said to weigh 23 GB.
Early Cartridges Opened the Door
The leak follows a familiar pattern. Physical copies of the remake began arriving at buyers’ homes several days ahead of release, and gameplay footage started appearing online by November 1. Those early cartridges gave hackers a head start, allowing them to access the game before most players could buy it. Some gamers posted videos of themselves playing the remake on social media.
Despite the dump, the game remains far from playable on PC. Emulators are struggling to render its graphics correctly. Users have reported washed-out visuals, black screens, terrain bleeding through objects, and inability to get past the title screen.
Tools Behind the Extraction
The dump is identified by title ID 0400486024DEC000. A report on the extraction names two tools: ns2jb and OunceCake. ns2jb is a software jailbreak developed by security researcher Sammy “pepsipu” Hajhamid.
Last month, Hajhamid explained how he got code running on the Switch 2 without a modchip. He said the exploit allows homebrew, reverse engineering and modding of Switch 2 games, backing up save files, and access to most peripherals through MMIO. He described it as the first such exploit for the console to his knowledge.
The jailbreak has limits. It is tethered, meaning it must be reactivated after the console restarts, and it does not provide unrestricted kernel access. The same extraction method has reportedly been used with Deltarune Chapters 1-4 and Mario Kart World.
A History of Switch 2 Exploits
This is not the first breach of Nintendo’s latest hardware. A day after the Switch 2 went on sale in June 2025, an exploit appeared that let hackers run custom code, though it did not offer root access or a full jailbreak. Cartridge-based backups have also caused problems. In August, Nintendo targeted more than 400 GitHub repositories, with 401 repos removed following seven Digital Millennium Copyright Act notices. Several Yuzu forks were among the affected projects.
Nintendo has not publicly commented on the Ocarina of Time dump or the ns2jb exploit. However, SmileBASIC 4, the application used to launch the jailbreak, has disappeared from the Nintendo eShop since the exploit was disclosed.
